In a peer review group, students can see and respond to each other's comments, but they cannot delete each other's feedback. Only the teacher, who is a moderator, can delete feedback. The final results of the worksheet are also visible within the peer review group. If you do not want students to see each other's final results, it is recommended that you disable the peer review group before the final results are formed. To do this, select None from the list when managing the peer review group.
